NHibernate 1.2 Beta 2 - Performance

time to read 1 min | 102 words

I was asked to help an application that was suffering un-optimal performance with NHibernate today. The first thing that I did was upgrade the application to NHibernate 1.2 (which took some time, damn non-virtual methods).

After I was done, I run the application, and was basically done. Just by upgrading to 1.2, we saw a major performance improvement. Now, to be fair, this is not just because NHibernate 1.2 is so much better (although it is :-) ). It is that it has different defaults (specifically about lazy loading) that make a huge difference in performance.
